IVILLIAM H. BURNS, OF S'I. LOUIS, MISSOURI.

PROPELLING AND STEERING VESSELS.

QPECIPICATION forming part of Letters Patent No. 338,162, dated March16, 1886.

(No model.)

To all whom it may concern.-

Be it known that I, IVILLIAM H. BURNS, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inPropelling and Steering Apparatuses, of which the following isafull,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification.

Figure 1 is a side view of the improvement when the screw-shaft is inline with the keel of the vessel. Fig. 2 shows the screw in end view,its shaft being at right angles with the keel. Fig. 3 is a detailhorizontal section at 3 3, Fig. 2, showing the propeller-screw and itssupporting-frame in top View.

A is the stern portion of a vessel, and B the keel.

0 and D are brackets in which the tillershaft '1 has bearing.

F is a tiller by which the tiller-shaft may be turned; butI do notconfine myself to this means of turning said shaft, as any device may beused for this purpose. Upon the tillershaft is fixed a frame, G, inwhich the shaft H of the propeller-screw I has bearing. Upon the shaft His a bevel cog-wheel, J, which engages a bevel cog-wheel, K, upon avertical shaft, L, which has hearing at the ends in the frame G, andwhose axis is in line with the axis of the tiller-shaft, so that theturning of the tiller-shaft does not affect the position of the shaft L.Upon the shaft L is a bevel cogwheel, M, which engages with abevel-wheel, N, upon the shaft 0, which is rotated by the steam-engine.

It will be readily seen that the propeller may have continuous rotationwhile the tillersteer the boat when the boat or vessel is passingthrough the water, and it will be seen that by means of the propeller,when in the position shown in Figs. 2 and 3, the boat or vessel may beturned around without having any endwise movement in the water.

An inclined position of the propeller is shown in dotted lines in Fig.3.

I have shown the frame G as little more than a simple frame, the. barshaving no great width in the plane of the frame; but it may be preferredto extend the frame so as to form a rudder, as shown by dotted lines inFigs. 1 and 3.

I am aware that it is not broadly new to secure a screw-propeller withinthe rudder-frame and connect it to the operating-shaft through gearing,and do not claim such, broadly, as my invention.

I claim-- In a steering-propeller, the combination of the brackets G andD, the oscillating frame G,

stepped into said brackets, the tiller-shaft E,

connected to the frame G, the short vertical shaft L, journaled at bothends in the frame G concentrically with its axis of oscillation, thepropeller-shaft H, journaled at its ends in said frame, thepropeller-screw secured to said propeller-shaft at a point intermediateof its journals, the beveled cog-wheel J on said propeller-shaft, theoperating-shaft 0, having the beveled cog-wheel N, and the beveled gearsecured to the vertical shaft L and connecting the operating-shaft withthe propeller-shaft, all constructed and arranged to operatesubstantially as set forth.
